TONGS.

SPECIFIGATIONfmmhig part of Letters Patent No. 677,616, dated July 2,1901.

Application filed March 7, 1901.

To all whom, it may concern.-

Be it known that I, LoUIs FREDERICK, a resident of Baldwin township, inthe county of Allegheny and State of Pennsylvania, have invented a newand useful Improvement in Tongs; and I do hereby declare the followingto be a full, clear, and exact description thereof.

My invention relates to an improvement in tongs for handling steelingots or any other objects to which it may be found applicable, itsobject being to provide a strong and durable form of tongs which will beeasily operated and compact in form, so that they may be used in placesWhere the space is limited.

To this end my invention comprises, gen erally stated, tongs consistingof the ordinary lifting arms or levers pivoted together in the customarymanner, a rigid support extending out from one of said arms, a linkjournaled in said support, the opposite end of said link being connectedto arms pivoted in the opposite arm or lever of the tongs, and a handlesecured to that end of the link which is journaled in the rigid support,whereby upon the turning of said handle the said link is thrown into thedifferent positions for opening and closing the tongs.

To enable others skilled in the art to make and use myinvention, I willdescribe the same more fully, referring to the accompanying drawings, inwhich Figure 1 is a perspective view of my improved tongs, the levers orarms being ex; tended to their widest positions. Fig. 2 is a frontelevation showing the tongs closed to grasp the ingot or other object tobe carried, the handle hanging in a vertical position; and Fig. 3 is asimilar View, the tongs being extended.

Like numerals indicate like parts in each of the figures.

The numerals 2 and 3 designate the suitable arms or levers of theordinary construction employed in such tongs, said arms being pivotedtogether, as at 4, and'the lower ends of said arms being provided withthe teeth 5-, which are adapted to grip the metal or other object to behandled.

Secured to the upper ends of the tong-levers 2 and 3 is the chain 6, aportion of which onlyis illustrated. Where the tongs are used Serial No.50,268. (No model.)

in handling of ingots or other large bodies, this chain is connected insuitable manner with a crane which is employed for handling the tongs.

Extending out from the upper end of one of the tong-levers 2 is a. rigidsupport consisting, in this instance, of the bars 7 8, said bars beingbolted or otherwise secured to the tonglever 2 in any suitable manner,so as to be held rigidly in position. of said bars 7 and S is thebearing 9, within which is journaled the shaft 10. Keyed or otherwiserigidly secured to the shaft 10 is the link 12, the opposite end of saidlink being pivotally secured by the pin 13 to the arms 14 15. Theopposite ends of these arms 14 and 15 are pivot-ally secured to thetong-lever 3 by means of the bolt or pin 16, so as to be free to swingthereon.

Formedintegral with or secured to the shaft At the outer ends 10, whichis journaled in the bearings 9 of the bars 7 and 8, is the extension 17,having the lug 18. This lug 18 fits within the bifurcated end 19 of theconnection 20, a pin 21 passing through the bifurcated end of saidconnectionand the lug 18. A lug 22 on the connection 20 is securedwithin the bifurcated end 23 of the hand-lever 24 by means of the pin25. This handle 24, so provided with a universal joint, may be of anysuitable length, and in order to provide a guide for said handle a rod26 is connected to the lug 27 on the bolt 28, which passes through thetong-lever 2, the

bifurcated end 29 of said rod 26inclosing the lug 27, with a pin 30 forsecuring said rod thereto. The outer end of the rod 26 is secured to theguide 31, said guide having the opening 32, through which the handle 24passes.

When my improved tongs are in use, they operate in the following manner:With the tongs in their open position (shown in Fig. 1) they are loweredinto position to grasp the ingot or other object to be lifted, whereuponthe operator lifts the handle 24 into a substantially horizontalposition, and by turning said handle in either direction the link 12moves in the arc of a circle, the shaft 10 upon which it is mountedbeing turned within the bearings of the rigid support formed of the bars7 and S. From this construction it will be apparent that it makes nodilference which ICO , ner described, with one end journaled in therigid position and the other pivotally secured to the arms 14 and 15, Iam enabled to give a wider movement to the tong-levers when operated toopen.

By having a rigid support within which the link 12 is journaled only onearm 26, extending from the tong-lever to the guide 31 on the handle, isrequired, and as a consequence the tongs may be lowered into thesoakingpits to grasp the ingot with greater ease, as there is no suchrod on the other side of the tongs,which permits of the tongs beingworked in a smaller space.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In tongs, the combination of tong-levers, of a link, a rigid supporton one of said tonglevers within which said link is journaled, aswinging support on the other tong-lever, a connection between saidswinging support and said link, and a handle connected to that end ofsaid link journaled in said rigid bearing.

2. In tongs, the combination with tong-levers, of a link, a shaftrigidly secured to one end of said link, a rigid support on one of saidtong-levers within which said shaft is journaled, a handle connected tosaid shaft, a swinging support on the opposite tong-lever, andconnection between said swinging support and the other end of said link.

3. In tongs, the combination with tong-levers, of bars rigidly securedto one of said tong-levers, a shaft journaled in the ends of said bars,a link rigidly secured to said shaft, swinging arms on the oppositetong-lever, connection between said swinging arms and said link, and ahandle connected to said shaft.

4. In tongs, the combination with tong-levers, of a rigid support on oneof said tonglevers, a link journaled in said support, a swingingsupport.on the opposite tong-lever, connection between said swingingsupport and said link, a handle connected to said link where it isjournaled in said rigid support, a guide on said handle, and a rodextending from said tong-lever having the rigid support to said guide onsaid handle.

In testimony whereof I, the said LOUIS FREDERICK, have hereunto set myhand.
